Precision Button Force-Displacement Analysis System

The S205 Keyboard Load-Stroke Curve Tester delivers laboratory-grade characterization of button mechanics through high-resolution load-stroke curve measurement (0.01gf resolution) with 100mm maximum stroke and servo motor precision control, enabling complete evaluation of:

Tactile feedback characteristics
Activation force points
Return spring performance
Life cycle degradation
